Detailed Description

The utility model aims at providing a steering shaft dust cover so as to solve the problem that the steering shaft dust cover occupies the space in a vehicle.

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-3, an embodiment of the present utility model discloses a steering shaft dust cover 10, comprising: a vehicle body engagement portion 11 for engagement with the vehicle body floor 20, a steering shaft engagement portion 12 for engagement with the steering shaft 30, and a cover portion 13 connecting the vehicle body engagement portion 11 and the steering shaft engagement portion 12. Wherein the cover body 13 has a V-shaped structure and the V-shaped opening is directed into the vehicle.

As shown in fig. 3, the steering shaft dust cover 10 has a body engaging portion 11 engaged with the body floor 20 and a steering shaft engaging portion 12 engaged with the steering shaft 30 to seal the perforated portion of the body floor 20 during actual use. Because the cover body 13 is of a V-shaped structure, and the V-shaped opening faces into the vehicle, in other words, the V-shaped bulge faces towards the vehicle bottom, the cover body 13 cannot bulge towards the vehicle, and the problem that the steering shaft dust cover occupies the space in the vehicle is solved.

In some embodiments, to achieve both the steering shaft dust cover 10 and the body floor 20 sealing, a snap-fit connection may be employed between the body mating portion 11 of the steering shaft dust cover 10 and the body floor 20. Specifically, as shown in fig. 2 and 3, the outer peripheral wall of the vehicle body engaging portion 11 may be provided with a first annular engaging groove 11a engaged with the vehicle body floor 20. During manufacturing, the steering shaft dust cover 10 can be made of rubber, and the vehicle body floor 20 can be well clamped into the first annular clamping groove 11a by utilizing the soft characteristic of the rubber, so that the steering shaft dust cover 10 and the vehicle body floor 20 are tightly combined, and the steering shaft dust cover is convenient to install and plays a role in fastening and waterproof.

As shown in fig. 2, the first annular clamping groove 11a includes a first groove surface 11a1 near the vehicle interior, a second groove surface 11a2 far from the vehicle interior, and a groove bottom 11a3 connecting the first groove surface 11a1 and the second groove surface 11a 2. Advantageously, the length of the first groove surface 11a1 is longer than the length of the second groove surface 11a2, so that the vehicle body floor 20 can be more conveniently clamped into the first annular clamping groove 11a during installation, and the installation is quite convenient.

As shown in fig. 2, a steering shaft guide ring 40 is provided in the center hole of the steering shaft engaging portion 12, and the steering shaft guide ring 40 has a steering shaft through hole through which the steering shaft 30 passes. In practice, the steering shaft guide ring 40 is in clearance fit with the steering shaft 30.

In order to facilitate the installation between the steering shaft guide ring 40 and the steering shaft dust cover 10, the steering shaft guide ring 40 and the steering shaft engaging portion 12 of the steering shaft dust cover 10 may also be engaged with each other. As shown in fig. 2, in some embodiments, an annular protrusion 12a may be disposed on an inner peripheral wall of a central hole of the steering shaft matching portion 12, and a second annular clamping groove 40a that is in clamping fit with the annular protrusion 12a may be disposed on an outer peripheral wall of the steering shaft guiding ring 40, so as to implement clamping connection between the steering shaft guiding ring 40 and the steering shaft matching portion 12, which is convenient to install and has a good sealing effect.
